I've no use for them. Not on the left, not on the right.
Yes, and all of those religions would have been considered crimes in
the Massechusetts Bay Colony during the witch-burning years.
Maybe so. But since you're questioning whether the morality of the ancient Greeks (those nasty idolaters!) is relevant, I have to ask: Of what relevance are the moral and spiritual preoccupations of the Puritans?
Am I to understand that you're asserting any and all Americans
who don't believe in god, but who are not necessarily atheists, are
presumed to be witches?
I suspect that the Puritans during the witch-burning years might well have considered them as such.
Again, I don't see how that speaks to the assertion being correct.
Even granting arguendo that this is true (ignoring, then, the deism of Jefferson or Franklin),
Even as they dissented, theologically, they did not publicly dispute
the Christian moral codes that were promulgated by believers.
You'll find that most people--even gay marriage supporters, even would-be married gays--don't dissent with the majority of those codes; contention is largely on the specifics. In the absence of any empirical evidence that the deity in question exists, the specifics matter.
In fact,
Franklin wrote that he ceased to promote deism when, after convincing a
friend of his of its truth, that friend no longer in fear for his soul
soon became an irresponsible scoundrel.
That friend was likely an irresponsible scoundrel to begin with. What's more, Franklin only notes ceasing to promote deism, not ceasing to believe in it.
Well, if the assumption has been ubiquitous, then why shouldn't I assume it?
Belief in the metaphysical bases of Buddhism was, and is, ubiquitous in the East, and becoming increasingly more so in the West. Why shouldn't you assume THAT belief is correct?
The answer: There's no reason you shouldn't. Unless you happen to believe something else, in which case it would be not only immoral, but unconstitutional, to insist that you abide by the tenets of that belief system.
Perhaps Christians strategically blundered when, for decades after
school prayer was overturned, they continued to support public
education.
How so? hould they be upset that those who don't adhere to your--their--belief system to learn how to read, write, and do math?
